Customers are pleased with this user-friendly home kit which generates results, including water hardness levels, within minutes, and the reusable TDS meter that comes with a battery. However, the test strips can only be used once. A number of users would also like the laboratory report to indicate the EPA limit for all the tested contaminants, not just some of them.
If we were to list out all the 50 contaminants that are tested by Safe Home Premium Drinking Water Test Kit, it would take up the rest of this review. These include 6 in-organics, 12 physical properties, and 32 toxic metals that are listed in detail at the back of the package. You will receive one in-home test to pre-screen results, including a bonus Safe Home DIY Bacteria test for Total Coliform and E. coli, and one mail-in to confirm results for a more analytical report.

The Company that has sold over three million tests also owns an EPA-certified laboratory for testing indoor and outdoor water sources. All you have to do is mail a sample of your water to the laboratory since the laboratory fees, and the cost of shipping your sample back is already covered in the initial purchase. The testing duration lasts from 7 to 10 business days after receipt, after which the results are emailed to you.
A certified lab report is sent directly to you with each test result and more information such as the MCL (Maximum Contamination Limits) for each contaminant tested and a color-coded ‘qualifier’ beside each test result indicating whether the tested contaminant is at a Safe Level, Questionable Level or Dangerous Level. However, some buyers found this comprehensive report complicated.
Health Metric Well Water Test Kit checks for 8 contaminants in water that can cause illness, corrosion, limescale buildup, and odor. The 9-strip kit includes 1 test for coliform bacteria like E. coli, 2 for nitrate and nitrite, 2 for manganese, 2 for hydrogen sulfide and 2 tests to check alkalinity, pH and hardness of your water. Prior to delivery, the manufacturer emails a user guide with a color-coded card to compare with your results.
Apart from the bacteria test, the other results will take 2 to 5 minutes. Customers like the straightforward process and the accuracy of this kit, which produces results that align with lab results such as the carried out at the Michigan Department of Community Health Laboratory.

A home kit saves you money on expensive lab tests and professional water testers.
This kit does not test lead, and a couple of buyers did not receive the test strips for hydrogen sulfide and nitrate nitrite.
Hard water as a result of calcium and magnesium deposits causes dry skin, mineral buildup in pipes and kettles, and a messy scum on your laundry.
To overcome this, Hach Total Hardness Test Kit, Model 5-B comes with a square glass bottle, a measuring tube, 0.1-gram measuring scoop and 2 reagents that use drop count titration to measure water hardness from 1 to 30 grain per gallon (gpg) as Calcium carbonate (CaCo3). It is the best-rated water hardness test kit by buyers who are impressed by its accuracy and ease of use.
The process is very simple, and it yields results in a few minutes. Measure out your water sample with the tube and put it in the bottle. Add one scoop of the purple reagent powder to the bottle and shake it to dissolve it. Add the clear reagent to this solution, drop by drop, and swirl as you count the number of drops it takes for the solution to turn into a blue color. One drop translates to harness level of one grain per gallon, with a higher number indicating high levels of hardness that would require a water softener. For instance, 15 drops is 15 gpg hardness. The color might turn pink at some point which means you have to continue adding the titrant until the solution turns blue.
This water test kit only tests for water hardness. It does not test iron and magnesium.
Most tests need to be carried out at room temperature for precise results, but Hone Forest Water Quality Tester offers a solution for fluctuating temperatures by incorporating a titanium alloy probe and Automatic Temperature Compensation (ATC) of 0-50℃ to ensure accuracy of ± 2% F.S.
The budget-friendly test kit also boasts of a large backlit LCD for easy viewing of results, auto-lock mechanism, and a 3-in-1 pen for measuring Total Dissolved Solids (TDS), Electrical Conductivity (EC) and the temperature of your water.
Testing for TDS will provide insight into hydroponics to check nutrient count for your indoor plants, and let you know whether your Reverse Osmosis Deionization system is effective and when your filter is due for replacement.
When you stir the water after turning on the TDS meter, the readings are auto-locked on the LCD display within a few seconds, and then the meter turns off automatically after more than 2 minutes of inactivity to conserve battery. You can also lock the reading manually by pressing “HOLD”.
This water test kit is powered by a CR5 Lithium battery. It comes with a TDS color chart, a protective leather case with a belt clip that allows you to check the water from anywhere, a 3-year warranty, and a 90-day money back guarantee.
The manufacturer recommends rinsing the probe with distilled water after each use to maintain accuracy.
We like the factory-calibration that saves time and effort, the large readout for readings, and its consistency. Unfortunately, it does not measure pH.

Features to consider while choosing a water test kit
The following are the key features that will guide you when choosing the best water hardness or lead test kit that will protect your health as well as your boilers and pipes from corrosion and blockage.
What it is designed to test
Water test kits differ in the type of contaminants they are able to detect and the compatible water sources. For a comprehensive range that will keep your water safe, consider a model that can test for several impurities and bacteria, and work with various types of indoor and outdoor water sources. With the exception of the Hach Total Hardness Test Kit, Model 5-B that only tests water hardness and the Hone Forest Water Quality Tester that measures the Total Dissolved Solids (TDS), Electrical Conductivity (EC) and the temperature of your water, all the other products we have recommended provide kits with enough strips to conduct one full test. The Safe Home Premium Drinking Water Test Kit and the Culligan Comprehensive Water Lab Test Kit even include additional mail-in tests that are sent to their laboratories for a detailed analysis.
How long it takes to conduct the test
The time it will take to carry out the test will depend on the type of water test kit and the type of contaminant they are detecting. For instance, bacteria such as Total coliform and E. coli require to be incubated for 48 hours at 35 ± 0.5ºC or 37 ± 0.5ºC according to the Water Quality Monitoring guide Trusted SourceWater Quality Monitoring - A Practical Guide to the Design and Implementation of Freshwater Quality Studies and Monitoring Programmes The discharge of wastes from municipal sewers is one of the most important water quality issues world-wide. It is of particular significance to sources of drinking-water. www.who.int by the United Nations Environment Programme and the World Health Organization. The 48-hour duration is also recommended by manufacturers of test water kits to ensure integrity of results. Otherwise, the Health Metric Well Water Test Kit produces test results for bacteria, nitrate, and nitrite, manganese, hydrogen sulfide, alkalinity, hardness, and pH in 2 minutes, and the Test Assured Drinking Water Test Kit takes 10 minutes to generate results when testing lead, bacteria, pesticide, iron, copper, alkalinity, pH, hardness, chlorine, nitrates, and nitrites.
Mail-in results take the most time, up to a week, due to the advanced laboratory tests and the detailed report that is emailed to you afterwards. You also have to factor in the shipping time.
Before buying the best lead water test kit, you need to confirm that the test is among those included in the kit. In this case, the Safe Home Premium Drinking Water Test Kit which tests 6 in-organics, 12 physical properties, and 32 toxic metals contaminants, including lead, would be a better choice rather than the Hone Forest Water Quality Tester which tests Total Dissolved Solids (TDS), Electrical Conductivity (EC) and the temperature of your water. For water hardness, bacteria and other contaminants, you can look at the Health Metric Well Water Test Kit that also tests nitrate and nitrite, manganese, hydrogen sulfide, pH, and alkalinity.
Another factor to consider is the number of tests you can perform with one kit. Some offer single-use strips whereas the Health Metric Well Water Test Kit comes with a 9-strip kit that includes one test for coliform bacteria like E. coli, two for nitrate and nitrite, two for manganese, two for hydrogen sulfide and two tests to check alkalinity, pH and hardness of your water. This allows you to test water from various sources such as wells and taps. Another multiple-use kit is Hach Total Hardness Test Kit which includes a square glass bottle, a measuring tube, 0.1-gram measuring scoop and two reagents that use drop count titration to measure water hardness from 1 to 30 grain per gallon (gpg) as Calcium carbonate (CaCo3), and allows you to perform up to 100 tests.
If it needs to be mailed
The best drinking water test kits that offer mail-in tests also come with DIY home tests that you can use to detect the contaminants in your water in a few minutes, although the bacteria test usually takes 48 hours. For mail-in tests, you take a sample of your water and send it to the specified laboratories for more accurate tests that take less than a week to receive a detailed lab report of the analysis. Along with the nine in-home testing strips, the Culligan Comprehensive Water Lab Test Kit also provides a water bottle where you put 200 ml water sample and prepaid mailer with free shipping to send the sample to Culligan’s NELAP-Certified Analytical Laboratory for further tests. It takes approximately 5 business days to receive the lab report. Another product with a mail-in option is the Safe Home Premium Drinking Water Test Kit which comes with two vials for the water sample to be sent to their EPA-certified laboratory. Both the laboratory fees and the cost of shipping your sample are covered in the initial purchase, and the detailed lab report is emailed to you within 7 to 10 business days.
While some home water test kits will only let you know whether your water has certain contaminants by giving you a positive or negative result, a professional report from a laboratory offers details on the exact levels of impurities in your water, and the EPA recommended limit for those contaminants.
To avoid compromising your health, you will need an effective product that can test your water for contaminants and produce accurate results. A defective product can produce false findings or fail to detect these impurities, so it is important to know that such unforeseen circumstances are covered by a long warranty. Most of the products we have featured in this review of the best home drinking water test kits come with appealing warranties with enticing money-back guarantee offers for unsatisfied customers.
